Justin Timberlake and Jimmy Fallon brought us all the way back to the sleep-away days in a gut-busting sketch on The Tonight Show last night that found them reliving their days as brace-faced adolescents with a penchant for '90s alternative rock. What began as a simple salute to the good ole camp days, eventually erupted into an all-out geek-out on Third Eye Blind's insanely popular single "Jumper" with two strangely grown campers and one counselor who just can't relate (and insists on wearing the shortest shorts you've ever seen.) Despite said counselor's efforts and some playful (hilarious) banter, the fellas just can't be stopped from belting out the chorus to their favorite summertime jawn. Even The Roots lend a hand towards the end to take them out with some musical muscle. Pepper in a few jokes about bodily changes, the fact that JT's rocking a full beard, and this makes for one helluva way to start the morning off. With a smile, of course. You can go ahead and watch Jimmy Fallon and Justin Timberlake geek out on some Third Eye Blind as metal-mouthed teens on The Tonight Show below.
